I have a few scratches that I'm going to repair. They didn't go all the way through to the fiberglass but seem fairly deep. Should I start out with a 600 grit and work my way up? I'm just concerned that it might be too deep and will need to be patched. I'll see if I can get some pictures up to give you a better idea.

600 is very aggressive. start with the least aggressive and go from there. After that, follow up by going all the way to the very least aggressive to get out most of the stratches left from the wet sanding. Then polishing compound. Try some compound by hand or polisher first before jumping to wet sanding. if its all the way through the colored gel, you will not get it out. just like auto paint.
